Tooll whom it may mam Be it known that I, WILLARD 0. WHITE, a citizen of the United States, residing at Uniontown, in the-county of Fayetteiand] State of Pennsylvania, have invented anew 1 and useful Door for .Coke-Ovens, 'of which the following is a specification. This invention has reference to improvements in doors or 'clgsuresfor coke ovens,

furnaces, and the likdiand while more particularly adapted to rectangular and beehive coke ovens it may be used with advantage in connection with otherovens or fire chambers. p

' The object of the present invention is to provide a device of this character. wherein the metal parts are protected from overheating while provision is made for supporting fire brick or like materialconstituting, the protecting material where the shapes of the fire bricks are such as to involve a minimum number-of special brick molds while the bricks may be of moderate size to economize manufacture and repairs.

Furthermore, the present invention provides a door in which both the brickand metal partsare free to expand without danger of warping the metal framework and the brick and metal parts are so combined that the metal is capable of radiating heat on the cool side of the door while those metal parts which are subjected to most heat are easily renewable.

The invention also provides means whereby the brick space of the door may be considerably varied in height and width and-- without necessitating variation in the size of the metal parts so that the same metal parts are adaptable to either the front or discharge ends of ovens where the discharge end is wider than the front or pusher end.

The showing of the drawings is that of an oven door for the rectangular type of coke ovens, such oven being provided with a door at each end.. For the beehive type of oven the arrangement of parts is practically the same but on a smaller scale. Other ovens or furnaces will. require slight modifications in structure but not of the invention. Therefore the invention is not limited. to the details of constructionshown and described but may be varied so long as the salient features of the invention are retained.

The invention will be best understood:

from a consideration of the following detail conipanyi ng drawings" forming a part of this specification, in. which drawings Figure 1 is a central vertical section through the door-and oven. Figs; 2, 3 and 4 are edge and face views respectively of a fire brick used in connection with the door. Fig 5 is a face view of an oven equipped with the present invention showing a modified form of-supporting means for the door.

Referring to the drawings there are shown two adjacent coke ovens 1, 2, the door ends only being, shown, and these ovensare assumed to be of the rectangular typewhere thev ovens are similar one to the other and arranged slde by side and in the particular instance shown, .one oven is illustrated as somewhat more elevated than the other, it being a common practice to form the entire bank of ovens on a slight incline.

It is customary to build the doors in two sections, an upper section 3 and a lower section 4.

' The upper section is a skeleton frame which comprises a plate 5 of appropriate size and shape with the lower edge having an inturned flange 6 terminating in an up turned rib 7 approximately parallel with the plate 5. The upper edge of the plate 5 is rounded in conformity with the arch of the opening of the oven.v

Attached to the upper end of the plate 5 is a bow plate or strip 8 provided at appropriate points with flat lugs or extensio-is 9 having at. the free ends slots or grooves 10 adapted to receive bolts 11 by means of which the bow plate 8 is made fast to the door plate 5 with limited adjustmentthereto. The bow plate 8 has along the edge remote from the lugs 9 a rib 12 "WhiCh when the plate 8 is made fast to the plate 5 is parallel with the said plate 5 but spaced therefrom by the width of the plate 8 and the thickness of the lugs 9.

The lower door member is provided with a metal skeleton frame comprising a plate 13 formed at top and bottom with longitudinal flanges 14, 15 respectively projecting at right angles to the plane of the plate 18 and terminating at the edges remote from the plate the plate 13 of the lower door are faced'on the fire side with fire bricks 17, one of which is shown in Figs. 2, 3 and 4 and this may be taken as typical of all'the bricks making up the fireside of the door, except that the arched edges of the bricks along the upper edge of the upper door are curved on substantially the arc of the arch of the oven. Each brick 17 has one face 18 of such area that when all the bricks of the doors are in place the fire side of the door will be practically continuous with the edges of the bricks forming closely fitting joints, although as will hereinafter appear, certain latitude in this respect is permissible. The other face 19 of each brick is of less area than the face 18 although of'equal length,

- the face 19 being of less extent in the direction of the height of the brick than the face 18. Along the top and bottom portions of the face 19 'where this portion of the brick joins the face 18 there is provided a longitudinal groove 20 while along those portions of the brick which are set vertical when in place on the door, there are provided grooves 21 for a purpose which will presently appear.

\Vhen the bricks '17 are in place on the door the vertical edges in which the grooves 21 are formed are in abutment throughout the thickness of the brick except where the grooves 21 occur, these grooves matching in the adjacent edges of the bricks. The top and bottom edges of the sides 18 of the bricks 17 are also in engagement where the bricks are adjacent, butthe like edges of the portions 19 of the bricks are separated by spaces determined by the height'of these portions 19 of the bricks, while the grooves 20 of one brick match the grooves 20 of adjacent bricks. The door is therefore formed of bricks in vertical series when the door is in place with the horizontal meeting edges having longitudinal channels formed by the meeting grooves 20. Seated in.these channels are bars 22 of metal and these bars are connected with the respective frames 5 and 13 by bolts 23 surrounded between the respective plates 5 and 13 and the bars 22 by spacing sleeves 24.

pt. e lg'e of the lower series of bricks 17 of the The rib 7 of the lower flange 6 of the door he, 5 engages the groove 20 on the lower toor 3 while the upper series of bricks 17 isfi enz aged by the bowed strip or plate with its rib 12' seated in the grooves 20of hese bricks, the other bricks intermethe top and bottom rows being held ars 22 and bolts'23 with theirspacand of the flange6 and also of the spacing sleeves 24 determine the distance from the oiiter face of the bricks l7 andthe inner face of the 'plate 5, this plate being off-set an appropriate distance" from the outer faces-of the bricks 17. The rib-12 of the plate 8 and the rib 7 of the flange 6 together with the bars 22 firmly anchor the, bricks 17 to the plate 5 of the upper door while the ribs 16 of the flanges l4 and 15, and the bar 22 firmly anchor the brieks'of the lower door to the plate 13. The bars 22 may be as long as desired and the plate 8 is capable of adjustment vertically wit-h relation. to the plate 5, considering the door as installed, and therefore doors varying considerably in size may be constructed without the necessity of providing other i tal parts than those described, one size or metal parts answering for doors of' different sizes.

\Vhen in .place the door 4 and the door 3 are superposed with the door 4 the lower door and resting on the floor of the oven. hen the bricks are assembled in the doors or door sections 3 and 4 the spaces provided by vertical grooves 21 in matching relation one to the other at the meeting edges of the bricks are filled with refractory packing so that these joints are rendered tight.

The construction described furnishes ample provision whereby the bricks may be readily replaced without the necessity ofentirely dismantling the door, and those metal parts liable to damage may also be readily replaced. At the same time no metal parts an subjected to the direct action of the heat'but are amply protected by the fire brick interposed between-these metal parts and the interior of the oven. Furthermore the metal supporting plates are spaced from the outer walls of the fire bricks so that transmitted heat has ample radiating space and the metal parts are correspondingly protected from the effect of the great heat of the interior of the oven.
